Coffee helps a bit with her daily activities but disrupts her sleep

Although drinking coffee helps her make it through the day, she feels anxiety and has noticed a hand tremor that was not present before. Besides that she feels intense heart palpitations and is a bit worried about how things are progressing. 

Mrs AP wonders what to do. She wants to be active during the day and she also needs her quality sleep. In the meantime, the whole situation makes her wonder, whether these heart palpitations and the tremor are symptoms of the pain medications. She is always afraid of medicines and she would very much prefer not to take any medication whatsoever. 

She realizes that she needs to go back to her GP and plan what to do, step by step.
